Webinjective function of N. It implies that all odd powers of Dehn twists ˝N are distinct, and so are all powers of Dehn twists ˝N. Note that for nodd, the Brieskorn manifolds ( N;2;:::;2) are all non-di eomorphic. Furthermore, such Dehn twists can be constructed for any symplectic manifold containing a Lagrangian sphere. WebSquared Dehn twists can be symplectically nontrivial Crucially, the small resolution cannot be done symplectically - away from the central bre, small pusho s (in green!) of the new holomorphic sphere have vanishing symplectic area. In view of this, Seidel gave a nice argument to see that a squared Dehn twist can be nonzero in ˇ 0(Symp(X)) for ...

This paper introduces a new Lagrangian surgery construction that generalizes Lalonde–Sikorav and Polterovich’s well-known construction, and combines this with Biran and Cornea’s Lagrangian cobordism formalism.
